Installation & Use
🛠️ Before installation, verify the complete 3S7700VB100A1 part number and compare the existing detector’s mounting arrangement, signal characteristics, and turbine monitoring-system configuration.
🔌 Inspect the sensor wiring, connectors, grounding, and signal path before commissioning. Check for damaged cables or loose connections that could produce false vibration indications.
📊 After installation, verify the vibration signal at the monitoring system and compare the measured value with the expected baseline. Confirm alarm and protection thresholds according to the approved turbine documentation.
⚠️ This component is associated with turbine vibration protection. Do not substitute a different vibration detector solely because the mechanical mounting appears compatible; sensitivity and electrical characteristics must be verified first.
